For a short time I’m having to use a Technicolor TF582n FTTC router whilst I rule out a hardware issue affecting my fibre connection.
THe DNS servers picked up by default don’t tend to be that great, so I prefer to use Google DNS servers. Here’s how I changed the addresses quickly via a telnet session.

dns server route list
dns server route flush
dns server route add dns=8.8.8.8 metric=10 intf=Internet
dns server route add dns=8.8.8.8 metric=10 intf=Internet
dns server route list
if happy

No need to reboot the router.
